i saw the duncan schematics before, none of them look like the push pull MG-70 i am trying to make sure is wired right..all the pups sound fine except for the bridge humbucker. is putting out very weak sound, no matter where i have the volume, tone or push pull. The black and white wires from bridge humbucker are both soldered together and to middle lug of DPDTany help appreciated..this guitar was inherited from a family member that died suddenly and it was his first electric guitar.am trying to get it back to as close to original as possible.
